Pro L

Completely filters air in a 72m² room every 12.5 minutes or a 173m² room every 30 minutes.

Clean air for a healthier, happier space

Quiet achiever
Noise-levels are no louder than a whisper on low speed (32 dB) and equivalent to the noise level of a quiet office on high (55 dB).
Advanced v-shape filter
Pro sports an advanced, v-shaped filter to maximize filter area, prevent premature clogging, and folds together like a book to minimize exposure to pollutants during replacement. The modular design allows you to add on the Carbon+ filter for light gas and odor removal.
Modular filters fit your needs
Stack the activated Carbon+ filter add-on on top of the standard Pro Particle filter for added gas and odor removal.
Optional sensor add-on
An optional add-on, the Air Intelligence Module (AIM) uses two smart sensors to test particle and gas levels in your indoor air and automatically adjusts the fan speed. Set to AUTO mode and AIM with automatically maintain the optimal clean-air environment.

Professional performance for extra-large rooms

Filters the air at the industry-recommended rate of 4.8x an hour (or about every 12,5 minutes) in a 72 m² room to effectively lower particle levels and maintain a comfortable environment in extra-large rooms, open-concept floor plans and studios. Pro L moves an impressive amount of air, delivering an airflow of 660 cubic feet per minute on high speed.
Designed for your workspace

The galvanized steel housing delivers maximum clean air delivery in a compact design, and the sleek white appearance is designed to blend in seamlessly in a professional environment.
The secret behind powerful filtration

Our unique combination of electrostatic and mechanical filtration that we call HEPASilent™ filtration technology sets us apart. The combination allows us to use filters that are less dense and require less air pressure than traditional HEPA filters without a loss in performance— resulting in quieter and more energy efficient air purifiers.
Superior clean air delivery

Designed to work as hard as you do, the Pro L is independently AHAM verifide for the maximum possible Clean Air Delivery Rate (CADR) of Smoke/>450, Pollen/>450, Dust/>400.
Low energy consumption

Limit energy costs and use 24 hours a day without concern (22-170 W).
